BECEPTACLE.

Application led April 9, 1924. v'ellalfo. 7052881.

This invention relates to receptacles, such as tubes, pails, firkins andthe like, designed for the packing, storage or transportation of various materials or commodities. It has to L; do particularly with receptacles 'fabricated ofyfibrous material, such Aas ypaper stock. Due to `various characteristics, such as Itheir lesser -Weight and cost and uniformity of size, receptacles of that type are, to an increasing extent, suppla-nting wooden receptacles in many uses. p

-While retaining the advantages of vlight Weight and low cost,`it is 'important that such receptacles possess great 4strength and stability, in order that the relatively less amount of material in ltheir 'structure be qualiiied lto withstand the stresses Aimposed upon them by the `Aweightof the contained material, 'handling'intransportation, and the Weight `of the receptacles or ypackages to which 4they are subjected when stacked in storage. One of'the `principal objects of the present invention, therefore, lcomprises certain improvements in the details lof construction of such articles, whereby their `strength and stability are increased effectively with out appreciable vincrease in weight or the amount of 4material required or increase in the cost of manufacture.

Another object is the improvement off-cer tain features in the construction of the -receptacles-which contribute to safety and convenienceiinfthe storage .and transportation of them by enabling their being stacked vwith security.

Still another object is the simplification lof the manufacture of articles of the `sort described.'

Other andfurther objectsof the invention will Y:be Apointed` out hereinafter, indicated in the appended claims, or obvious to :one skilled in the art upon an understanding of the present disclosure. For the purpose of "this application I have Velected to disclose certain structures, `which I present as illustrativey of fthe invention, and are not to be construed as llimiting what I purport to sevcure,..short noithe true and most comprehensive scope ofthe invention inthe art.

In the drawing forming a ypart of this specification,

Fi 'il is a partial sectional elevation taken on t e diameter of two tirkins or pails, shown in the relationships in which they are `customarily vstacked in storage and transportation, with one resti-ng on top of 'the other;

Y Fig. 3 is a detail in the nature ofapart sectional elevation l'of certain apparatus .and one of ithe elements of the receptacle structure, :illustrating a `step -in the "forming of the Alatter Fig. 4 is a similardetail illustrating a subu sequent step in the "rnanufac'ture off the receptaclegand n Fi .f5 is a detail 'in the -nature'of a megniiie` -seotion-ofa wall :portion of -a receptacle.

The 'nature of 'the invention will be lunderstood-best *by reference to the illustrative disclosure in detail. Referri'ngto thed-rawing,wlet it be understood that the reference numeral l() designates `the wall ortion of a receptacle, lthe same being ormed of fibrous materialsueh vas paper stock, preferably builtupofaplurality-ofllayers or laminations. 'In tactual practice, this may #be Y made relatively ftliin, approximately oneeighth of an yinch ina receptacle "having a capacityo Yfive-gallons ior more. sIt is of certain lcommercial advantage to have the receptacles of truste-conical form. The wall portion maybe formeda'fter the fashion de scribed :in the patent to John Strange, No. 11,198,596, "granted V*Se Vtomber 19, 1916. The smaller end of the by a bottom 511 of -fsi-rni ar structure. 'This bottom is vretained against `upward move- Vment by a hoopfl'l fitting closely 4Within the bo'dy l ortion and `contacting at its lower `margin t e peripheral portion of the bottom; A supporting rin 14 v'is `fitted within the Wallportionbelow t e bottom, and contacts fthe latter vbelow its `marginal r.por-tion. The hoop 12 and/ring 14 preferably are made 'of "the same virn'tterial as the lWall portion, -afterfthe fashion described yin the 'pat- `ent above mentioned.y With this assembly is combined a `-retaining ring made of sheet Vmetal and formed with the constraining `flange 15, the 1binding 2flange 16 .and the supporting '17. The constrainin flange is continuous vand formed yon suc radius as yto closely encompass the wal-1 portion 150. It is of such "depth as to overlap the peripheral margins of the bottom 1/1 and a `portion kof odY portion is closed' the. height of the hoop 12. The binding flange 16 is of such length as to overlap the bottom margins of the wall portion and the supporting ring 14, while the supporting flange 17 fits closely within the supporting ring and extends up within the same into marginal contact with the lower surface of the bottom 11. At intervals, the supporting flange is provided with short projections 18 extending away from the ring 14. These, together with the marginal portion of the supporting flange, supplement the ring 14 to give increased supporting area for sustaining the bottom 11. The supporting and constraining flanges bear such relationship that the lower part of the wall portion and the ring 14 are supported and confined between them, said flanges conforming respectively 'to the internal taper of the ring 14 and the external contour of the body portion. At intervals about the receptacle staples 19 are inserted to secure together the constraining flange, the wall portion and hoop 12. The binding flange 16 is traversed by a series of radiallyextending depressions 20, which are pressed in the metal.

i Certain features of the structure, as well as the method of producing it will be understood by reference to Figs. 3 and 4. In the production of the retaining ring, a hoop is first formed from a strip of sheet metal, said hoop being of the approximate diameter of the outerI surface of the lower portion of the wall. This hoop is placed on a forming mandrel M and spun over the flange fm, thereof by 'means of a suitable spinning roller R. The top of the flange m is transversely serrated to mate with the Vknurling r of the spinning roller, so that the co-action of the two forms the depressions 20. Inasmuch as the spinning operat-ion folds the marginal portion of the metal hoop inwardly, parts of the metal are forced into puckers or convolutions, which form the projections 18. rhe ring when thus formed is removed from the mandrel M and fitted on to the lower margin of the receptacle, as above described. 1f completely formed in the spinning operation, so as to have an accurate fit, the ring may then be secured in place by insertion of the staples 19. If not completely formed in the spinning operation, itmay be further shaped, after application to the body, by suitable means S and S. This operation may be Vperformed v in such fashion as to flatten down portions of the projections 18, thus giving the flange 17 an expansive tendency which contributes to the tightness of the assembly. The staples 19 anchor the constraining flange securely in place, opposing any tendency, which may be given it by the expansion of the supporting flange 17, to flare away from the wall portion 10. The resulting structure possesses great strength and rigidity at the important joint between :incarne the bottom and the side Wall, all of the component parts being bound positively together and retained in the desired contour by the stiff channel structure resulting from the arrangement of the flanges 15, 16 and 17.

heretofore employed, a top closure 21 is provided for the receptacle, the same having the depending flange 22 which receives the upper marginal portion of' the wall 10. A pair of stiftening members 24 are disposed in crossed relationship on diameters vof the top closure, being secured to the latter by suitable means Over these' are stretched wires 26 which are secured at their ends to loops in a girth wire 27 encompassing the receptacle. 1n the storage of packaged commodities, it is important that the packages lend themselves conveniently to stacking. 1n the present improvements advantage is contributed by the arrangement of the retaining ring with its radial bottom depressions 2O for co-operation with the wires 26, as such affords a form of connection between superin'iposed packages which facilitates their being stacked in straight piles, prevents their rotation upon one another and prevents their sliding off one another. The corrugation of the binding flange by the depressions 20 also serves to stiffen it transversely and thereby aid in retaining the shape of the supporting flange.

Certain improved features of the wall structure are illustrated in F ig. 5. As illustrated, the wall may be made up of the three laminations y10, 10b and 10, as above described. To these, on the interior, is added a composite lamination formed of sheets 1()d of flexible material, such as paper, and an intermediate binder stratum 10? of Waterproofing adhesive material, such as asphalt. 1n the manufacture of the receptacle, the composite lamination is first made up in sheets, which sheets are then cut to the proper shapes and combined with the other laminations. The waterproofing layer 10e is effective to prevent or retard the pene-tration of moisture into the receptacle through the walls thereof, or into the laminations 10, 10" and 10U from the interior of the receptacle.
